The Lenovo 3000 N200 is a great budget laptop, picked mine up for £349 a few days ago. I recommended it to a friend who was buying a new laptop, and liked theirs so much I bought one myself.
The graphics card isn't great for gaming but for a sub £400 laptop you cant expect much better, and you need to upgrade the 1gb of RAM to atleast 2gb or Vista runs like a dog. I picked up an extra 2gb stick for £30, made a big difference.
It's got a few nice integrated extras too Wifi, Bluetooth, Camera, Card Reader and Fingerprint Reader.
